Download Path for Driver (Question)

[ottogutierrez]

Hello, I'm currently trying to use undetected_chromedriver in AWS as a lambda function.

So far, I have created the layer with the "undetected_chromedriver" library included. However, as I understand, the library automatically downloads the correct driver according to the machine. Since it is running in an AWS lambda function, it appears that only the '/tmp/' folder is available (Linux based system).

Is there a way to modify the download folder for the chromedriver?

This is the error I encounter

Traceback (most recent call last):
File "/opt/python/lib/python3.7/site-packages/undetected_chromedriver/patcher.py", line 252, in __del__
if self._custom_exe_path:
AttributeError: 'Patcher' object has no attribute '_custom_exe_path'
[ERROR] OSError: [Errno 30] Read-only file system: '/home/sbx_user1051'

Thanks!

I think this would get resolved with #643. Thanks!

hi @ottogutierrez ! Maybe I'm facing the same problem as you. can you give me some tips? thank you very much!
i use python3.7
selenium==3.9.1
undetect-chromedriver=3.5.0
chrome-driver==2.31
headlesschrome==v1.0.0-41

there is my code:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options


chrome_dir = '/opt/chrome'
chrome_path = chrome_dir + '/headless-chromium'
chrome_driver_path = chrome_dir + '/chromedriver'

def create_undetected_driver():
    import undetected_chromedriver as uc
    from undetected_chromedriver.options import ChromeOptions
    chrome_options = ChromeOptions()
    chrome_options.add_argument('--headless')
    chrome_options.add_argument('--no-sandbox')
    chrome_options.add_argument('--single-process')
    chrome_options.add_argument('--disable-dev-shm-usage')
    chrome_options.add_argument("--disable-gpu")
    chrome_options.binary_location = chrome_path
    return uc.Chrome(driver_executable_path=chrome_driver_path,
                       headless=True,
                       options=chrome_options,
                       use_subprocess=False,
                       user_data_dir="/tmp")

def lambda_handler(event, context):
    """The actual function that will be called"""
    driver = create_undetected_driver()
    try:
        url = 'https://nowsecure.nl'
        driver.get(url)
        image = driver.get_screenshot_as_base64()
        return {
            'headers': { "Content-Type": "image/png" },
            'statusCode': 200,
            'body': image,
            'isBase64Encoded': True
        }
    finally:
        driver.quit()
    
    return {
        'statusCode': 200,
        'body': json.dumps(str(event))
    }

the error:
[ERROR] OSError: [Errno 38] Function not implemented
Traceback (most recent call last):
